To uZZ whom it away concern:

Be it known that we, REUBEN ARK- wnioi-rr and ISAK MonLLna, subjects ofthe King of Great Britain, residents of the city of New Glasgow,Province of Nova Scotia, Dominion of Canada, have invented certain newand useful Improvements in Unconpling Devices for Freight Cars, of whichthe following is a specification.

This invention relates to improvements in uncoupling devices for freightcars, and is a divisional application of United States applicationSerial No. 381,311, filed May 11th, 1920, and the objects of theinvention are to permit of the link mechanism of the uncoupling deviceautomatically adjusting itself relatively to the position of the couplerpin, when the coupler is in its inner or outer position, and generallyto adapt the uncoupling device to better perform the functions requiredof it.

Vith the above and other objects in view, the invention consistsessentiallyof the improved construction particularly described 25 andset forth in the following specification and accompanying drawingsforming part of the same.

In the drawings:

Figure 1 is a fragmentary end elevation of a freight car showing theimproved uncoupling device mounted thereon.

Figure 2 is a fragmentary side elevation of the freight car showing theimproved uncoupling device thereon.

Figure 3 is a detail in plan showing the arm of the uncoupling rod.

Figure 4: another detail showing an alternative form of end.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings; A represents a freight car of any usualdescription provided with a coupler B carrying a coupler pin C, and asthe several parts so far enumerated are well known in the art it is notdeemed necessary to further describe the same.

According to the present invention a derice is utilized for actuatingthe pin C and this consists of an uncoupling rod formed at the outer endwith an offset hand grip 11, the inner end being bent at right angles tothe rod to form an arm 12 which overhangs the pin C, the arm 12 beingbent laterally at right angles to form a retaining end 12.

The uncoupling rod 10 is journalled in suitable brackets 14: and as thehand grip 11 is rotated the arm 12 will be rotated in a vertical plane.

The arm 12 is connected to the pin C by a link 15 provided with atransverse arm 16 which passes through and pivotally engages with thehead of the said pin, and the arms of the link are provided at the upperend with hooked portions 17 which are bent around and embrace the arm12.

It will be evident that as the arm 12 is rotated in a vertical plane thelink 15 will slide on the same and will automatically adjust itselfrelatively to the position of the pin C. The outward movement of thelink 15 is restricted by the turned end 12 In Figure 41 an alternativeform of un coupling rod is illustrated in which the arm 12 is providedat the outer end with a turned back portion 12 which forms an elongatedorifice and the link 15 is slidably mounted on the arm 12 but the offsetend 12 of the arm controls the sliding movement of the link and onlyallows a displacement sufficient to permit of the link 15 automaticallyadjusting itself relatively to the couples pin C.

lVhen a car equipped with this type of uncoupling device is in use, theoperator stands at the side of the car and actuates the hand grip 11 torotate the uncoupling rod so that the link 15 controls the movement ofthe pin C.

In the alternative form of end shown in Figure 4: the end 12 after beingturned laterally is bent to form an elongated eye.

As many changes could be made in the above construction, and manyapparently widely difierent embodiments of our invention within thescope of the claims constrncted without departing from the spirit orscope thereof, it is intended that all matter contained in theaccompanying specification and drawings shall be interpreted asillustrative and not in a limiting sense.

What we claim as our invention is:

In a device of the class described, the combination with a couplerprovided withv a locking pin having an eye, of an operating rod havingan outwardly extending arm, the end of said arm being bent backwardlyfor forming a link retaining loop, and a single link having at its lowerend an elongated 100p supported at both sides and at its upper end hooksturned inwardly for engaging the arm, the loop on the arm permittingsliding movement ofthe link in 1611- gitndinal direction but limitingthe amount of movement both forw'zirdly and rear- 10 Wardly.

In Witness whereof we have hereunto set our hands.
